The Role of Medical and Legal Gender Affirmation in Shaping Positive Mental Health Outcomes for Transgender and Gender Diverse People in Australia

Purpose: Transgender and gender diverse ("trans") people often face stigma and discrimination, leading to mental health challenges. Gender affirmation, including social, legal, and medical aspects, can alleviate these challenges. However, the mental health outcomes associated with legal gender recognition remain under-explored, particularly in an Australian context. Therefore, this study examines associations between different forms of gender affirmation and mental health outcomes among a large sample of Australian trans adults.Methods: We analyzed data from 1,359 trans adults responding to a national survey conducted in late 2019 in Australia. Measures included demographics, gender affirming care access, hormone therapy, legal affirmation, psychological distress, suicidal ideation, suicide attempts, and gender euphoria. Logistic regressions assessed associations between gender affirmation factors and mental health outcomes, accounting for sociodemographic variables.Results: Access to gender affirming care was associated with reduced psychological distress, decreased recent suicidal ideation, and increased gender euphoria. Legal gender affirmation was correlated with lower psychological distress and increased gender euphoria. Participants desiring hormone therapy but not accessing it reported higher psychological distress.Conclusion: Our study highlights the positive impact of gender affirmation on the mental health of trans adults. Access to medical and legal gender affirmation were both associated with lower psychological distress and higher gender euphoria. These findings stress the importance of timely access to gender affirmation when desired. Further research should explore nuanced effects across affirmation pathways, informing inclusive health care and legal frameworks.
